If you have been using the Typewriter tool in previous versions of Acrobat/Reader you will notice it is no longer available under the Tools menu in Acrobat/Reader X.
The Typewriter tool has been renamed to “Add or Edit Text Box” and relocated in Acrobat X following extensive research by our product teams. A lot of people were having issues trying to find these tools in previous versions. Particularly with the younger generation, some did not even know what a typewriter was.
To locate/use the Typewriter tool in Acrobat X:
1. open a PDF
2. click on the “Tools” menu on the right-hand side
3. expand “Content”
4. click “Add or Edit Text Box”
A new feature in Acrobat/Reader X allows you to add commonly used tools to the Quick Tools bar. If you right-click on the “Add or Edit Text Box” button, and select “Add to Quick Tools”, then you will see the icon appear on the toolbar as follows:
Note: If you are using Adobe Reader, the “Add or Edit Text Box” tool is not available until you enable the PDF with extended rights.

If you are using Acrobat XI then you can watch the following video to see how to enable the typewriter tool:
